Is it possible to build a bridge that connects the UK with the US?

This sort of reminds me of a joke:

A biker finds a magic lamp and rubs it. A genie appears and grants him a single wish. He wishes for a bridge connecting California to Hawaii, so he can ride his bike back and forth between the two places. The genie says "Are you nuts? A project that large would consume several of Earth's resources, not to mention the disruption to wildlife migration patterns and ocean currents. No, it's too much. Ask for something else!"

So the biker says "Okay, I want to understand women. I want to know what they mean when they say nothing is wrong. I want to know what makes them cry, what makes them laugh."

The genie ponders for a moment then says "Hmmm, you want that bridge to be two lanes or four?"

Okay, joking aside...it is THEORETICALLY possible to build a bridge across the Atlantic Ocean (or the Pacific), but it would be an engineering challenge greater than anything we've ever achieved as a species. The ocean is too deep to build columns all the way to the floor, so you'd have to build floating supports tethered in place by cables. That's daunting enough, but there would have to be a lot of flexibility in the bridge to accommodate waves and the tides. Plus, the bridge would have to be made of some kind of material - perhaps aluminum - that would resist corrosion.

And here's the worst part...nobody would use it. It would certainly have to be a toll bridge to pay for construction and upkeep, and the tolls would be enormous. It'd be cheaper to buy a plane ticket. It'd also be faster to fly. It's about 3000 miles from New York to the UK. Even if the speed limit on the bridge was 100 miles per hour, that's still 30 hours of driving. You can fly from NY to London in less than 8 hours, and kick back and relax while you do it.

So...while I do think it is within our technological capability to build such a bridge, I can't think of any good reason to do so.

I hope that helps. Good luck!

This is an engineering forum. Theoretically it might be possible to build such a bridge but engineers don't deal in the theoretical but deal in in what is real, practical and possible.

Sure. We can build floating oil platforms, all we'd need is thousands of those with bridges between them. Totally impractical and I wouldn't care to cross in a storm.

None of the usual bridge building methods would survive the storms, so it would not be completed. Google launch loop. The proposed track would be above all the storms, and can likely be modified to meet usual definitions of bridge.

Yes you can build that bridge. Where would you like to start and when?

This is your dreaming idea that nobody wants to invest in this silly project even we do have this technology.

I think the material would have to be governmentium...the densest material known.
